This photograph was actually taken the day after the scene described below. This photograph is also the last in “Volume One” of “Street Prostitute: Photographing Ronda.” “Volume Two” will begin as soon as I get moved in and settled in my new home in Florida. Thanks to all of you for your interest in “Volume One” and your helpful and kind comments. I hope you will continue viewing the series whenever I am able to begin “Volume Two….” (In meantime, I will continue uploading other photographs.) 10:30 P.M. "George, this is Tim G______." His voice sounds grim. "I'm calling from Grady Hospital," he says. "Ronda's here, and it looks like she's gonna be here for a while." "What's wrong with her?" I ask. "They say she's got a staph infection and a heart murmur." "What room is she in?" "Still in the emergency room." "I'll be right down." As I'm throwing on some clothes, I wonder: Should I take my camera? My recorder? No, I reluctantly but quickly decide. Because if I do, Ronda might think that the only reason I've come is to document the event for the book. In ten minutes, I'm parked near the county hospital for indigents—a mammoth hulk of a building. Hurrying on foot past the ambulances and police cars jamming the rampway to the emergency room, I look down just in time to avoid stepping in a puddle of blood. Once inside, the first person I see is Tim. (Note: Tim is a trick of Ronda’s, an educated middle-class social worker who knows Ronda well, and who told me during a long interview that he is in love with her; and, according to Ronda, offered the other day to take her away from it all and move up to the mountains with him.) He's down in a squatting position right outside the doors to the emergency room. His face is buried in his hands. He looks up at me with eyes wet from tears. He stands and leads me through one of two huge swinging doors into the emergency room. The place is like a tunnel. A long and windowless tunnel. Lining both walls are stretchers. Every one appears to be occupied, and every one of their occupants appears to be black and elderly. Nurses and orderlies, doctors and police officers are bustling here and there — mostly in and out of the examining rooms, which run the length of the right-hand side of the corridor. Tim and I proceed onward...until, about halfway down, Tim stops and points to the open door of one of the examining rooms. I take a few steps further, peer in, and there see Ronda.. . ...Who looks awful. She's in a raised-up hospital bed, an IV protruding from her neck.... She's holding a teddy bear—Joey, her favorite. With both arms, she’s clutching him tightly to her chest. Also in the room is a man in white—a doctor no doubt. Standing with his back to Ronda, he is writing something... working, I realize at that second, on her chart. Tim waits outside in the tunnell while I go on in and stand beside Ronda in her bed. "Hi, George," she says, her voice weak but warm. "Hi, Ronda..." I start to hold her hand...hesitate... But then I go ahead: I put my hand over hers, holding it. "How're you doing?" "I'm worried about Melvin," she answers. "What's Melvin gonna do?" "Ronda, I think you should be concerned about yourself right now," I tell her. I glance at the doctor, his back still to us. "Dr. Grumwald?" Ronda catches his attention. "I'd like you to meet George Mitchell," she says as he turns. "He's the one I told you about that's writing the book about me." "What's the situation?" I ask him. He is handsome, tall and curly-haired. In his early thirties. "All we know for sure right now—" [his demeanor serious]—"is that she has an infection of the skin called cellulitis. Which is usually caused by dirty needles. But she could also have endocarditis. We're running tests for endocarditis now." As the doctor is talking, Ronda slowly moves her hand from underneath mine. I've held it, I realize, a little too long for her comfort. I bring out my notepad. "En—do—car—di—tis? What's that?" "An infection of the heart valve," says Dr. Grunwald. "Bacteria gets on the heart valve, and it sits on the valve and chews it up. It is extremely serious, and if she has it, we might have to do open heart surgery. To replace the heart valve.” He takes a breath. “And I want to impress upon Ronda—and upon you—just how serious the situation is." With that, he leaves the room. Ronda groans. "A nurse took a blood sample from here"—she gingerly places her hand over her abdomen—"and she messed up and hit a bone." I wince... "Is it hurting?" "Hell yeah, it's hurting!" her voice pick

This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a "borderless world", cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in terms of latent demand) for each major city of the world. It then ranks these cities and reports them in terms of their size as a percent of the country where they are located, their geographic region (e.g. Africa, Asia, Europe, Middle East, North America, Latin America), and the total world market.

In performing various economic analyses for its clients, I have been occasionally asked to investigate the market potential for various products and services across cities. The purpose of the studies is to understand the density of demand within a country and the extent to which a city might be used as a point of distribution within its region. From an economic perspective, however, a city does not represent a population within rigid geographical boundaries. To an economist or strategic planner, a city represents an area of dominant influence over markets in adjacent areas. This influence varies from one industry to another, but also from one period of time to another.

In what follows, I summarize the economic potential for the world's major cities for "power-operated, on-off mounted actuators for gates, globes, angles, Y-type straightway check, stop and check, cross, 3- and 4-way, and other industrial valves" for the year 2009. The goal of this report is to report my findings on the real economic potential, or what an economist calls the latent demand, represented by a city when defined as an area of dominant influence. The reader needs to realize that latent demand may or may not represent real sales.
